Rigging of an asymmetrical scaffolding piece: the lifting beam is blue, the load is attached to the beam using grey slings. The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another. The bottom ...
The spreader is placed between the container and the lifting machine. [1] The spreader used for containers has a locking mechanism at each corner that attaches to the four corners of the container. A spreader can be used on a container crane, a straddle carrier and with any other machinery to lift containers. Spreader operation can be manual ...
A level spreader is an erosion control device designed to reduce water pollution by mitigating the impact of high-velocity stormwater surface runoff. It is used both on construction sites and for permanent applications such as drainage for roads and highways .

A spreader is a spar on a sailing boat used to deflect the shrouds to allow them to better support the mast. [1] The spreader or spreaders serve much the same purpose as the crosstrees and tops in a traditional sailing vessel.
Part of the design of the B&R rig involves inducing a "pre-bend" in the mast which provides some of the side-to-side and fore-and-aft stability of the rig. [2] [3] [4] The pre-bend is achieved by tensioning the reverse diagonals and certain other so called intermediate shrouds. Because the spreaders are swept back at approximately a 25° to 30 ...
Figure 1: (a) This simple supported beam is shown with a unit load placed a distance x from the left end. Its influence lines for four different functions: (b) the reaction at the left support (denoted A), (c) the reaction at the right support (denoted C), (d) one for shear at a point B along the beam, and (e) one for moment also at point B. Figure 2: The change in Bending Moment in a ...
The spreader's design can vary, ranging from conventional single-boom spreaders to more modified two-conveyor compact spreaders. The main parts of a spreader usually come in four signature parts. The first is the signature receiving boom with or without a support crawler track. The second is the main body superstructure itself.
